Question

DESIGN and COMPLTE a program ACCORDINGLY that determines final letter grade for a student with encouraging comment. Three exams and two assignment scores as well as the student name will be entered by the user. Every score should range from 0.00 – 100.00. The program will give user only one chance to correct invalid score and provide meaningful feedback. Exams and assignments have equal weights for the final score (i.e. 50% by each category) that determines the final grade. Final grade and comment are determined by the following scale: A – 90 or above (Excellent!!) B – between 80.00 – 89.99 (Good job!) C – between 70.00 – 79.99 (Happy? Not happy?) D – between 60.00 – 69.99 (Could be better, right?) F – below 60.00 (Could be improved next time?)
